We all run into legacy code. Sometimes, we even write it ourselves. Working with legacy code can be a daunting challenge, but there are ways to tackle it without taking on the risk of a full rewrite.
There is a deep satisfaction that comes from conquering a nasty piece of legacy code. The ability to achieve this goal depends on both testing and refactoring.
We'll learn how baby-step refactoring techniques lead to a better understanding of the code and a high-quality design while always keeping the code running.
This is a workshop, so a lot of the material was hands-on practice and not captured in these slides.
